The germ cloud from your sneeze can travel 20 feet

Posted: Updated:

If you're like me you got sick in the winter and you don't want a repeat this spring. So you've stocked up on hand sanitizer, tissues, and vitamins.

New research from M.I.T. shows that may not be nearly enough to keep you from catching a cold. An animation shows what really happens when you sneeze. You may see some droplets but that comes with a cloud of invisible gas that can travel the length of an average room -- 20 feet or more -- and the height of a ceiling right where the ventilation system is.

I could be typing at my desk when I sneeze. The invisible sneeze gas cloud could get sucked into the ventilation system and spread to other rooms and other people in the office.

M.I.T. researchers believe these findings will be especially significant for hospitals.

The study shows architects and engineers may want to re-examine the design of ventilation systems to try to control the spread of germs.
